Hello group,
One quite tricky question.
In the IEWB Lab 18 Q12.1 there is an example on how we should configure a router to response with its Loopback address when any other router issue a traceroute to it.
What if we want to do something slightly different.
What I want is to traceroute from R1 to R5.
R2 has 2 possible ways to reach R5. These are R3 and R4. See the diagram below:
R1 ------- R2 ------------------R3-----------------
| |
| |
| |
R4--------------------------------------R5
I want this traceroute to go through R4 and not through R3.
My configuration is the following:
R2:
ip local policy route-map test
!
route-map test permit 10
match ip address 100
set ip next-hop <R4-address connected to R2>
!
access-list 100 permit icmp any any time-exceeded
access-list 100 permit icmp any any port-unreachable
Local policy routing is configured because traceroute is locally generated by the router each time.
However, I can not get this to work.
Any ideas ?
TIA
Varthis
